How to Convert Kubernetes Manifests into Nomad Jobspecs

1

Nomad Project

Ever since I started exploring Nomad, one of the things that I’ve enjoyed doing is taking Docker Compose files and Kubernetes manifests, and translating them into HashiCorp Nomad jobspec. I did it for Temporal back in March 2022, and also for an early version of Tracetest, back in the summer of 2022.

kubernetes-deploy

As I mentioned earlier, the rendered YAML manifests for the OpenTelemetry Demo App are available to us here. Since, for the purposes of this tutorial, we only care about the featureflagservice’s Kubernetes manifest, I’ve gone ahead and grabbed the manifest pertaining to the featureflagservice, which is made up of a Deployment and a Service, as per below.

Consul

By default, the service is registered to Consul. Although we don’t explicitly say so, it’s the equivalent of adding a provider = "consul" attribute to the service stanza. You can register your services to either Nomad or Consul.
